This invention relates to an ,apparatusl for washing milk of magnesia.

'With this and other objects in view, the invention consists in certain novel features of construction as hereinafter shown Iand described, and specifically pointed out in the Iclaims.

In the accompanying'drawings.

Figure 1 represents a vertical central section of the apparatus constituting this in vention.

Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1, and

- Fig. 3 is a similar view taken on the line 3 3 .of Fig. 1.

v'Milk of magnesia as is well known, ie Mg(OH) ,-l-aqua. Ordinarily the ingredients which constitute the milk of magnesia are stirred or mixed to ther -in a large container several times arger th the amount to be made, sucient distilled water being added to ll the container,

which is .left to stand from thirtysix to forty-eight hours. All of the water is then drained ed Aand more added da by day until the mixture is freed from t e sodium or magnesium. sulfates which are formed from the reaction of the ingredients used in the preparation of milk of magnesia. This method requires from two to three months to obtain the milk of magnesia used in commerce. The apparatus constituting this invention has been designed to reduce the timefor washing such milk and consists in placing the milk pf magnesia in a containerfsuchr as that shown at 1 in the accompanying drawin and then-v admitting air under pressure l1nto the bottom of the ofI magnesia. Water is then forced through. fthe bottom of the f container to free the sul-v container for mixingy and agitating the milk fates which are carried of 'by the water,` but the -water 'before leaving the container ,is filtered to retain` the milkl of magnesia mixture whichjis freed fromf the soluble sulfates 1 and other 'undesirable materials.

. The app'aratus'emploged .for carrying out e container. 1y which l this process comprises ,are clampingl is preferably in the form of 'a c linder havin a hopper-like bottom 2 with a water in ety pipe 3 opening through the apex thereof. This pipe `3 is provided with a control valve?)a shown clearly in Fig. 1. The

end of the pipe which is disposed in the lower end of the hopper-like bottomf2 of the container has arranged thereover a combined cone-shaped spreader and deflector 4 which is mounted on suitable pins 4..

At Ithe junction ofthebottom 2 with the body of the container is an annularange -5 apertured for attaching the container to a suitable support shown at S.

A drain cock or'faucet 6 opens through one side wall of the bottom 2 near its lower end for drawing of the contents of the container.v

An air supply pipe 7 extends obliquely through one side wall ofthe containerl into the bottom 2 and terminates at its inner end at a point adjacent the water spreader 4 against which the air admtted therepasses through the ingredients in the container effecting a thorough mixing thereof. This pipe 7 is provided outside of the container 1 with a control valve 8 for admittin and cutting oi the air under pressure which is designed to be supplied through the P ghe upper end of the body of the container 1 is provided with an outstandmg laterally projecting flange 9 and a top 1 0 for the container has a similar flange 11 at its lower end between which and Han e 9 secured a filtering dis 12 and a forammous disk 13,' as is shown clearly in Fig. 1, clamps 14 being. shown for securing them together, adjusting screws 14 being shown' forv securing the clamps in operative position.

A water outlet pipe 15 opens through one side wall of the ltop 10, andy is designed f or conducting od' the filtered water to a suitable place of deposit.-v

In the use of the apparatus, the ingredients forming the Vmilk of*y magnesla are placed inthe container andI sub'ected to compressed air supplied throug 'lpe 7 within thecontainer at the bottom ereof.

After, the in redients have been subjected.

to compresse air,water underl pressure is supplied b Ythe pipe 3 ,which enters the con- `talner att Ae bottom thereof, and the Water rises through yand ,washes lthe mixture, vthen lthrough impinges and is broken up and 30 passes through the ltering disk l2 and toraminous disk 13 and is discharged through the medium of the pipe 15 at the top of the container'.

The process carried out by the apparatus above described accomplishes as much in one day of eight hours under equal conditions as the old process will in sixty.days. lit will thusbe `seen the time consumed for carrying out the process is greatly reduced.

, rllhe preferred embodiment of the invention is disclosed in the drawings and set forth in the specifications, but it will be understood that any modiications Within the scope of the claimed invention may be made in the construction Without departing ail fromtlie principle ot the invention or sacricing any of its advantages.
